ABSTRACT

OBJECTIVE@#To investigate the expression of Ca2+/calmodulin-dependent protein kinase II (CaMK Ⅱ) in pancreatic tissues of mice with severe acute pancreatitis (SAP) and explore the protective effect of KN93, a CaMK Ⅱ inhibitor, against pancreatic injury in SAP and the possible mechanism.@*METHODS@#Thirty-six healthy male C57 mice were randomly divided into sham operation group, SAP group, KN93 group and SAP + KN93 group (n=9). Serum and pancreatic tissue samples were collected 24 h after modeling. The pathological changes in the pancreatic tissues were observed using HE staining. Serum lipase and amylase activities and the levels of inflammatory factors were detected using ELISA. Western blotting was used to detect the expressions of CaMK Ⅱ, p-CaMK Ⅱ, p-NF-κB, MAPK and p-MAPK in mouse pancreas.@*RESULTS@#Compared with those in sham operation group, the expressions of p-CaMK Ⅱ, p-NF-κB and p-MAPK were significantly increased in SAP group (P < 0.05). KN93 treatment obviously alleviated pathological injuries of the pancreas in SAP mice, and significantly lowered serum levels of lipase, amylase and inflammatory factors (TNF-α and IL-6) and phosphorylation levels of NF-κB, ERK and MAPK proteins (P < 0.05).@*CONCLUSION@#The activity of CaMK Ⅱ is significantly increased in the pancreatic tissue of SAP mice. KN93 can alleviate pancreatic injury and inflammation in SAP mice possibly through the ERK/MAPK signaling pathway.

ABSTRACT

Abstract In China, Scutellaria is used for treating inflammatory-related diseases. Baicalin is the main active component of Scutellaria and has protective effects on acute pancreatitis. However, the mechanism of Baicalin is still unclear. In this study, the protective effects of baicalin on acute pancreatitis induced by taurocholate and its mechanism are investigated. In this study, mice were randomly divided into three groups: sham operation, model, and treatment groups. Acute pancreatitis in mice was induced by intraperitoneal injection of taurocholate (35 mg/kg). The treatment group was given baicalin (100 mg/kg) 2 h before acute pancreatitis induction. The mRNA expression levels of miR-429, nuclear factor kappa B65(NF-kB65), toll-like receptor 4(TLR4), TNF receptor associated factor6 (TRAF6), NF-kappa-B inhibitor(IkB), Follistatin-like 1 (FSTL1), and interleukin-1 receptor-associated kinase (IRAK) in the liver tissues 24 h after intraperitoneal injection were detected by RT-PCR. Then, the expression levels of NF-kB65, p-NF-κB65, TLR4, TRAF6, IkB, FSTL1, IRAK, p- IRAK, and p- IkB-а proteins were detected by Western blot. IL-6, TNF-α and IL-1 ß in plasma were measured by ELISA, and histopathological changes in the pancreases of the mice were observed. The results showed that after baicalin treatment, miR-429 expression in the pancreatic tissues and the expression levels of NF-kB65, TLR4, TRAF6, p-IkB-а, FSTL1, and p-IRAK decreased. Similarly, pancreatic myeloperoxidase (MPO) activity and the plasma levels of IL-6, TNF-а, IL-12, IL-1ß1, endotoxin, serum amylase, and lipase were reduced. Thus, the pancreatic injury induced by taurocholate was alleviated. The present study indicates that pretreatment with Baicalin can alleviate acute pancreatic injury induced by taurocholate in mice. The mechanism may be associated with the decreased miR-429 expression, reduced FSTL1 signaling pathway activity, TLR4 and TLR4/MyD88 signaling pathway inhibition, and reduced pancreatic inflammation. FSTL1 is the regulatory target for miR-429

ABSTRACT

La pancreatitis aguda o crónica puede resultar en lesiones del conducto pancreático, además, la corrosión por el jugo pancreático puede provocar la ruptura de la pared vascular periférica, lo que conduce a hemosuccus pancreático (HP) definido como el sangrado del conducto pancreático a través de la ampolla de Vater. El sangrado suele ser intermitente, repetitivo y, a menudo, no lo suficientemente grave, como para causar inestabilidad hemodinámica. La mayoría de los pacientes tiene antecedentes de enfermedades pancreáticas originales y cuando esto no se cumple, debe incluirse en el diagnóstico diferencial para alcohólicos crónicos con hemorragia digestiva alta intermitente. Presentamos una forma clínica atípica en un paciente masculino de 55 años de edad, con antecedentes de HTA, alcoholismo y aneurisma de la aorta abdominal, quien consultó por dolor tipo cólico en abdomen superior, náuseas y vómitos; luego se asoció disminución del estado de conciencia, alternando con episodios de agitación psicomotriz y primo convulsión generalizada. Una vez ingresado, sucedieron varios episodios de melena. La tomografía abdominal mostró aumento de tamaño y densidad (unidades hounsfield de 58-61) en cabeza y cuerpo del páncreas, por lo que se realizó una angiografía abdominal con protocolo de páncreas y se evidenció doble lesión aneurismática de la arteria esplénica y la arteria gástrica. Falleció en el postoperatorio(AU)


Acute or chronic pancreatitis can result in lesions of the pancreatic duct; in addition, corrosion by the pancreatic juice can cause the rupture of the peripheral vascular wall, which leads to pancreatic hemosuccus defined as bleeding from the pancreatic duct through the Vater ampulla. Bleeding is often intermittent, repetitive, and often not severe enough to cause hemodynamic instability. Most of the cases have a history of strictly pancreatic original diseases, when this is not the case, the PH should be included in the differential diagnosis for chronic alcoholics with intermittent upper gastrointestinal bleeding, We report here an atypical presentation in a 55-year-old male patient with a history of hypertension, alcoholism and an abdominal aortic aneurysm. He consulted for colicky abdominal pain in the upper abdomen, nausea and vomiting; subsequently he presented decreased consciousness, alternating with episodes of psychomotor agitation and generalized seizures. Once hospitalized he had several bouts of melena. The abdominal tomography showed an increase in the size and density (hounsfield units of 58-61) of the head and body of the pancreas. An abdominal angiography with a pancreas protocol was performed, which evidenced a double aneurismal lesion of the splenic and gastric arteries. The patient died after surgery(AU)

ABSTRACT

Introducción: La elastografía guiada por ultrasonografía endoscópica es considerada una herramienta útil en la evaluación de las lesiones solidas pancreáticas (LSP). Objetivo: El objetivo del estudio fue evaluar el rendimiento diagnóstico de la elastografia en pacientes con LSP. Material y métodos: Se realizó un estudio transversal prospectivo en el hospital Rebagliati durante julio 2017 a junio 2018. Se incluyeron pacientes con diagnóstico de LSP y estudio ecoendoscópico, elastografía y toma de PAAF. Se realizó elastografia cualitativa y elastografia cuantitativa (SR e histograma) y se analizó con resultados histopatológicos para determinar la sensibilidad, especificidad, valor predictivo positivo (VPP), valor predictivo negativo (VPN) y exactitud diagnostica en la detección de malignidad. Resultados: De 846 ecoendoscopías, se estudiaron 46 pacientes con LSP con una edad promedio de 64,6 años, 29 (63%) sexo femenino. El adenocarcinoma pancreático fue diagnosticado en 36 casos (78,3%). En elastografía cualitativa predominó el score 3 (n=39, 84,8%) con una sensibilidad, especificidad y exactitud de 88.9%, 30% y 76,1% respectivamente para predecir adenocarcinoma. Elastografía cuantitativa de SR≥ 15 (sensibilidad 100%, especificidad 66,7% y exactitud 97,8%) y un valor de histograma menor de 49 (sensibilidad 66,7%, especificidad 97,6% y exactitud 95,6%) predice malignidad en una LSP con área bajo de la curva ROC de 0,941 (IC 95%, 0,82 - 1,0). Conclusiones: La elastografía brinda información para predecir la naturaleza maligna de la lesión. En nuestro estudio la detección elastográfica de un score 3, SR≥ 15 o un histograma < 49 predice la presencia de malignidad en la LSP estudiada.


Introduction: endoscopic ultrasonography (EUS) elastography is considered a useful tool for the evaluation of solid pancreatic lesions (SPL). Objective: The aim of our study was to evaluate the diagnostic performance of elastography in patients with SPL. Material and methods: A prospective, cross-sectional study was performed at the Rebagliati Hospital between July 2017 and June 2018. Patients with a diagnosis of SPL and echoendoscopic study, elastography and FNA were included. Qualitative and quantitative elastography: strain ratio (SR) and strain histogram, were performed and analyzed with histopathological results. The diagnostic accuracy of EUS elastography in detecting malignancy was calculated using receiver operating curve analysis. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for the detection of malignancy were calculated. Results: Out of 832 EUS examinations performed, 46 patients with SPL (mean age, 64.6 years; 29 women) were included in the study. Pancreatic adenocarcinoma was diagnosed in 36 cases. In qualitative elastography, score 3 was most frequent (n = 39, 84.8%) with sensitivity, specificity and accuracy of 88.9%, 30% and 76.1%, respectively, for predict adenocarcinoma. A strain ratio of 15 or higher (100% sensitivity, 66.7% specificity and 97.8% accuracy) and a histogram of less than 49 (66.7% sensitivity, 97.6% specificity and 95.6% accuracy) predicts malignancy in SPL, with area under a ROC curve of 0.941 (95% CI, 0.82 - 1.0). Conclusions: EUS elastography provides information to predict the malignant nature of the pancreatic lesion. In our study, the elastographic detection of a score 3, SR≥15 or a histogram <49 predicts the presence of malignancy in LSP.

ABSTRACT

IgG4 related disease is a systemic autoimmune disease, which can affect different organs. The most common digestive manifestation is autoimmune pancreatitis (AIP), followed by involvement of bile ducts and the major papilla. The stomach is only rarely involved. We report a 71-year-old diabetic woman consulting for jaundice and weight loss. Abdominal CAT scan, cholangio resonance imaging, endosonography and a serum IgG4 of five times the normal value, lead to the diagnosis of an autoimmune pancreatitis. An upper gastrointestinal endoscopy showed a diffuse thickening of gastric folds. The pathological study confirmed the presence of IgG4 positive plasma cells. The patient was successfully treated with steroids.

ABSTRACT

Caspase recruitment domain-containing protein 9 (Card9) is located upstream of the nuclear factor kappa B (NF-κB) and p38 mitogen-activated protein kinase (MAPK) inflammatory pathways. This study investigated the therapeutic effect and potential mechanism of pioglitazone in rats with severe acute pancreatitis (SAP). SAP was induced by a retrograde infusion of 5.0% sodium taurocholate into the biliopancreatic duct of Sprague Dawley rats (n=54), which were then treated with pioglitazone. Blood and pancreatic tissues were harvested at 3, 6, and 12 h after SAP induction. Pancreatic pathological damage was evaluated by hematoxylin and eosin staining. Serum amylase, serum pro-inflammatory cytokines, and pancreatic myeloperoxidase (MPO) activities were determined by enzyme-linked immunosorbent assay. The expression of Card9 mRNA and protein in pancreatic tissues was detected by real-time polymerase chain reaction and western blotting. Pioglitazone had a therapeutic effect in treating rats with SAP by decreasing the level of amylase activity, ameliorating pancreatic histological damage, decreasing serum pro-inflammatory cytokine levels and tissue MPO activity, and downregulating the expression of NF-κB, p38MAPK, and Card9 mRNAs and proteins (P<0.05). The present study demonstrated that the inhibition of Card9 expression could reduce the severity of SAP. Card9 has a role in the pathogenic mechanism of SAP.

ABSTRACT

Summary Ménétrier's disease is an extremely rare disease of unknown etiology causing gastric mucosal hypertrophy and protein-losing gastropathy. Rare cases of this condition have been reported in patients with autoimmune diseases. However, to the best of our knowledge, Ménétrier's disease associated with autoimmune pancreatitis (AIP) has never been reported. We described a case of severe hypoproteinemia as a harbinger of Ménétrier's disease associated with AIP. The patient was successfully treated with octreotide and high-protein diet, which led to symptomatic remission and significant improvement in serum levels of albumin and recovery of the nutritional status. Thus, in AIP patients presenting with severe and persistent hypoproteinemia without apparent cause, clinicians need to consider Ménétrier's disease in the differential diagnosis. In this setting, endoscopic evaluation with histological examination of gastric biopsy material, including a full-thickness mucosal biopsy of involved mucosa, may be helpful in promptly establishing the diagnosis and allowing appropriate and timely therapy.


Resumo A doença de Ménétrier é uma condição extremamente rara, de etiologia desconhecida, caracterizada por hipertrofia da mucosa gástrica e gastropatia perdedora de proteína. Casos raros dessa patologia têm sido relatados em pacientes com doenças autoimunes. Até o momento, desconhecemos qualquer relato dessa doença associada à pancreatite autoimune (PAI). Descrevemos um caso de hipoproteinemia grave como indicador de doença de Ménétrier associada à PAI. O paciente foi tratado de forma satisfatória com octreotide e dieta hiperproteica, alcançando remissão sintomática, melhora significativa das concentrações de albumina e recuperação do estado nutricional. Portanto, em pacientes com PAI e hipoproteinemia grave e persistente, deve-se considerar a doença de Ménétrier como um diagnóstico diferencial. Nesses casos, a avaliação endoscópica com biópsia gástrica, incluindo biópsia de toda a espessura da mucosa, pode ser útil no estabelecimento do diagnóstico e do pronto início da terapêutica.

ABSTRACT

ABSTRACT The effects of rheum on serum parameters in a taurocholate-induced acute pancreatitis (AP) rat model were investigated using pathological and biochemical tests, and a proton nuclear magnetic resonance (1H NMR)-based metabonomic strategy. Healthy rats and rats with AP were either treated with rheum (7.5% at a dose of 1.5 g/kg) or left untreated. Serum samples were collected from the AP and rheum-treated groups at 6, 12, and 24 h after treatment. The effect of rheum on pathological changes in the pancreatic was investigated to validate the AP model. We obtained 1H NMR spectra and analyzed the results using the partial least squares discriminant method. The results of the pathological and metabolic analyses revealed an amelioration of multiple metabolic abnormalities and an increase in the aerobic respiration ratio after treatment, compared with the AP groups. These results were attributed to improvements in energy supply and the elimination of metabolic products. The study also promoted NMR-based metabonomic analysis as a feasible method of assessing traditional Chinese drugs.

ABSTRACT

ABSTRACT PURPOSE: To investigate the severity of pancreatitis in lipoprotein lipase (LPL)-deficient hypertriglyceridaemic (HTG) heterozygous mice and to establish an experimental animal model for HTG pancreatitis study. METHODS: LPL-deficient HTG heterozygous mice were rescued by somatic gene transfer and mated with wild-type mice. The plasma amylase, triglyceride, and pathologic changes in the pancreas of the LPL-deficient HTG heterozygous mice were compared with those of wild-type mice to assess the severity of pancreatitis. In addition, acute pancreatitis (AP) was induced by caerulein (50 µg/kg) for further assessment. RESULTS: The levels of plasma amylase and triglyceride were significantly higher in the LPL-deficient HTG heterozygous mice. According to the pancreatic histopathologic scores, the LPL-deficient HTG heterozygous mice showed more severe pathologic damage than the wild-type mice. CONCLUSIONS: Lipoprotein lipase deficient heterozygous mice developed severe caerulein-induced pancreatitis. In addition, their high triglyceride levels were stable. Therefore, LPL-deficient HTG heterozygous mice are a useful experimental model for studying HTG pancreatitis.

ABSTRACT

ABSTRACT PURPOSE: To investigate the therapeutic effects of ellagic acid on L-arginin ınduced acute pancreatitis in rats. METHODS: Thirty-two were split into four groups. Group 1 (control) rats were performed only laparotomy, no drugs were administered. Group 2 (control+EA) rats were administered 85mg/kg EA orally. Rats were sacrificed by cardiac puncture 24 hours after the administration. Group3 (AP) 24 hours after intraperitoneal L-arginine administration, rats were sacrificed by cardiac puncture. Group 4 (EA)-(AP): 85mg/kg EA was administered orally after the L-arginine administration. 24 hours later, rats were sacrificed by cardiac puncture. Serum TNF-α, IL-1β, IL-6, total oxidative status (TOS), total antioxidant capacity (TAC), amylase levels were determined in all groups. RESULTS: Group 3 (AP) rats showed significantly raised TOS level as compared to Group1 (control) rats (p<0.001). Following the EA therapy, a decrease in TOS was observed in Group 4 (AP+EA). TAC levels were significantly raised in the Group 4 (AP+EA) compared to the Group 3 (AP) (p=0.003). Group 3 (AP) showed significantly increased TNF-α, IL-1β and IL-6 serum levels as compared to Group 4 (AP+EA). Histopathological changes were supported our result. CONCLUSION: The healing effects of ellagic acid on inflammatory and oxidative stress were confirmed by histopathological and biochemical evaluations of the pancreatic tissue.

ABSTRACT

Galunisertib (LY2157299), a selective ATP-mimetic inhibitor of TGF-β receptor I (TGF-βRI), is the only known TGF-β pathway inhibitor. In the present study, we investigated the effect of galunisertib on taurocholate (TAC)-induced acute pancreatitis (AP) in rats, and the role of TGF-β and NF-κB signaling pathways. AP was induced by infusion of TAC into the pancreatic duct of Sprague-Dawley male rats (n=30). The rats (220±50 g) were administered galunisertib intragastrically [75 mg·kg-1·day-1 for 2 days (0 and 24 h)]. Serum IL-1β, IL-6, TNF-α, amylase (AMY), lipase (LIP), and myeloperoxidase (MPO) levels were measured by ELISA. NF-κB activity was detected by electrophoretic mobility shift assay (EMSA); NF-κBp65 and TGF-β1 proteins, as well as TGF-βRI and p-Smad2/3 proteins, were detected by western blot assay. Cell apoptosis was detected by TUNEL assay. H&E staining was used to evaluate the histopathological alterations of the pancreas. Galunisertib treatment attenuated the severity of AP and decreased the pancreatic histological score. In addition, number of apoptotic cells were significantly increased in the galunisertib-treated group (16.38±2.26) than in the AP group (8.14±1.27) and sham-operated group (1.82±0.73; P<0.05 and P<0.01, respectively). Galunisertib decreased the expression levels of TGF-βRI and p-Smad2/3 and inhibited NF-κB activation and p65 translocation compared with the sham-operated group. Furthermore, serum IL-1β, IL-6, TNF-α, AMY and LIP levels and tissue MPO activity were significantly decreased in the galunisertib-treated group. Our data demonstrate that galunisertib attenuates the severity of TAC-induced experimental AP in rats by inducing apoptosis in the pancreas, inhibiting the activation of TGF-β signals and NF-κB as well as the secretion of pro-inflammatory cytokines.

ABSTRACT

BACKGROUND/AIMS: Practice guidelines from international societies have recommended cholecystectomy during the same hospitalization for acute biliary pancreatitis (ABP). The aim of this study is to investigate the question of whether endoscopic sphincterotomy (EST) and/or cholecystectomy during the same hospitalization can reduce the recurrence rate of ABP. METHODS: A total of 119 patients with ABP admitted to our institution between May 2005 and May 2010 who had complete follow-up data until May 2012 were enrolled. RESULTS: No significant differences in initial CT severity index and Charlson comorbidity index were observed between EST (n=64) and non-EST group (n=55) and among subgroups classified according to interventions performed. In Kaplan-Meier analyses, significantly higher recurrence rates of ABP were observed in the non-EST group compared to the EST group (p<0.01), and in the conservative treatment group compared to other intervention groups (p<0.01). The frequency of complications from ABP was significantly higher in the conservative treatment group (35.7%) and lowest in the EST plus cholecystectomy group (5.0%, p=0.008). In multivariate analysis, conservative treatment without EST and/or cholecystectomy, and non-EST group were independent risk factors for recurrence after the initial attack of ABP. CONCLUSIONS: ERCP with EST and cholecystectomy during the index admission is associated with reduced recurrence rates of ABP.

ABSTRACT

To compare the efficacy of different types of solutions (Belzer or Euro-Collins) for the preservation of rat pancreas during cold ischemia. METHODS: Thirty Wistar rats were divided into three groups according to the perfusion or storage solution: Group E (perfusion and storage in Euro-Collins solution); Group B (perfusion and storage in Belzer solution) and Group BE (Perfusion in Belzer solution and storage in Euro-Collins solution). After perfusion, the pancreas was excised and stored at 4˚C for 18 hours. Amylase was measured at 6, 12 and 18h, and histological analysis of the pancreas was performed after 18h of cold storage. RESULTS: Amylase was elevated and comparable in Groups E and BE after 12 and 18 hours of ischemia (p<0.05). In the exocrine pancreas, histological differences in the amount of necrosis (p=0.049), lymphocytic infiltrate (p<0.001) and neutrophilic infiltrate (p=0.004) were observed, with more favorable features present in Group B. In the endocrine pancreas, Group B showed less edema (p<0.001), but other parameters were similar among all groups. CONCLUSION: The Euro-Collins solution is inferior to the Belzer solution for the preservation of rat pancreas during cold ischemia.

ABSTRACT

Introduction: Fistula formation between a pancreatic pseudocyst and the biliary tree is uncommon. Clinical case: We report a 71 years old female who developed a pancreatic pseudocyst secondary to a biliary acute pancreatitis. After eight weeks of evolution, the patient was operated due to the size of the pseudocyst and the presence of symptoms. During the operation, a fistula between the cyst and the biliary tree was found. It was successfully excluded performing a choledochostomy with a Kehr tube and pseudocyst drainage. The patient had an uneventful postoperative evolution and imaging studies at the moment of discharge, one month after the operation, did not show a residual cavity...


Introducción: Los pseudoquistes pancreáticos pueden desarrollarse tras episodios de pancreatitis, pudiendo originar diversas complicaciones como infección, hemorragia, fenómenos compresivos o fístulas pancreáticas. En el caso de estas últimas, la comunicación de un pseudoquiste pancreático a la vía biliar es una rareza, existiendo hasta la fecha sólo 19 casos reportados en la literatura. Caso clínico: Presentamos el caso de una paciente de 71 años que desarrolló un pseudoquiste pancreático posterior a pancreatitis aguda biliar y que debido a su tamaño y síntomas se decide el tratamiento quirúrgico a las 8 semanas. Durante la cirugía se diagnostica una fístula entre el pseudoquiste y la vía biliar principal, realizándose exclusión exitosa con coledocostomía con sonda Kehr, colecistectomía y drenaje del pseudoquiste, debido a la imposibilidad de derivación al tubo digestivo por friabilidad de su pared. La paciente evoluciona favorablemente, siendo dada de alta al mes de la cirugía. El control con imágenes previo al alta revela la desaparición del pseudoquiste, sin cavidad residual...

ABSTRACT

La infección por Mycoplasma pneumoniae (M pneumoniae) puede producir manifestaciones pulmonares y extrapulmonares a nivel cardiológico, dermatológico, neurológico, hematológico, musculoesquelético y gastrointestinal (vómitos, diarrea, hiporexia, dolor abdominal, hepatomegalia, hepatitis aguda, colecistitis alitiásica, y pancreatitis aguda). Presentamos un caso de infección aguda por M pneumoniae que se manifestó con neumonía, pancreatitis aguda y hepatitis colestásica. Paciente masculino de 15 años, con clínica de neumonía y dolor abdominal con elevación de pruebas hepáticas, amilasa y lipasa, y cambios sugestivos de pancreatitis aguda por ultrasonido abdominal y tomografía de abdomen y pelvis con doble contraste. El paciente evolucionó satisfactoriamente con el tratamiento indicado. Es importante considerar la posibilidad de infección por M. pneumoniae en pacientes con cuadros infecciosos respiratorios y manifestaciones digestivas sobre todo elevación de amilasa y enzimas hepáticas. Se describe el primer caso en nuestro país de pancreatitis y hepatitis asociada con infección por M. pneumoniae y el segundo en la literatura internacional


Mycoplasma pneumoniae (M pneumoniae) infection can cause pulmonary and extrapulmonary manifestations such as: cardiac, dermatological, neurological, hematological, musculoskeletal and gastrointestinal (vomiting, diarrhea, decreased appetite, abdominal pain, hepatomegaly, acute hepatitis, acalculous cholecystitis and acute pancreatitis). We report the case of a 15 years old male with pneumonia, abdominal pain, elevated liver tests with hyperamylasemia, elevated lipase, and changes suggestive of acute pancreatitis on abdominal ultrasound and double contrast CT scan of the abdomen and pelvis. The patient did well with the indicated treatment. It’s important to consider M pneumoniae infection in patients with respiratory disease and digestive manifestations including elevated liver tests and hyperamylasemia. To our knowledge this is the first case reported in our country of M pneumonia associated with pancreatitis and hepatitis and the second one in the literature

ABSTRACT

As lesões sólidas do pâncreas são constituídas, na maioria dos casos, pelo adenocarcinoma ductal. Contudo parcela considerável de casos apresentam lesões de outra natureza, as quais requerem abordagens cirúrgicas menos extensas ou tratamento clínico conservador com quimio ou corticoterapia. Neste relato, apresentamos o caso de uma paciente de 56 anos com icterícia e uma massa na cabeça do pâncreas mimetizando um quadro neoplásico. O diagnóstico de pancreatite autoimune foi firmado por meio da ecoendoscopia associada à punção aspirativa (AU)


Solid lesions of the pancreas are, in most cases, constituted of the ductal adenocarcinoma, but a considerable portion of cases have lesions of a different nature, which require less extensive surgical approaches or conservative medical treatment with chemotherapy or corticosteroids. In this report, we present the case of a 56-year-old female patient with jaundice and a mass in the head of the pancreas mimicking a neoplasm. The diagnosis of autoimmune pancreatitis was confirmed by endoscopic ultrasound-guided fine needle aspiration (AU)
